Charting the emergence of a ‘knowing system’ for climate change adaptation in Australian regional natural resource management

Climate change increases the complexity and uncertainty of regional natural resource management (NRM), calling into question the appropriateness of linear knowledge-transfer approaches. In this paper we reflect on knowledge practices among a partnership of researchers and NRM planners, under a federal program of NRM investment intended to ‘deliver information’ to regional NRM planners to support planning for climate change. We unpack ‘container’ and ‘conduit’ metaphors of linear, one-way communication invoked by the starting conditions, and explore whether more relational ways of communicating were achieved. A key theme emerged early in the research that NRM planners felt overwhelmed by the sheer volume of information available and discouraged by the irrelevance of much of it to their climate change planning. Our research-practice collaboration unfolded in this context and through ongoing face-to-face and virtual engagement over a period of two years. The collaborative approach featured joint identification of priority activities, co-design of planning approaches, and the iterative co-development of an online ‘information portal’, which acted as a boundary object. We report the emergence of a ‘knowing system’, resulting from these efforts to foster relationships and co-produce boundary objects in a particular geographic context. Our findings highlight the potential benefits of investing in the capacity of researchers and NRM practitioners to engage in collaborative research partnerships premised on the emergence of knowing systems.     

Emergence of co-management governance for Hawai‘i coral reef fisheries

Governance failures associated with top-down management have spawned a myriad of institutional arrangements to engage resource users in decision-making through co-management. Although co-management can take many forms and may not always lead to positive outcomes, it has emerged as a promising governance option available to meet social and ecological goals. Recent research on co-management of small-scale fisheries has used comparative approaches to test factors associated with social and ecological success. Less is known however, about how co-management institutional arrangements emerge and persist in the face of socioeconomic and environmental change. Here, we examine the emergence of co-management governance using a case study from coral reef fisheries in the Hawaiian Islands. We used a mixed methods approach, combining a robust policy analysis and a set of key respondent interviews to trace the evolution of this co-management arrangement. Our research uncovers a set of linked drivers and social responses, which together comprise the emergence phase for the evolution of co-management in this case study. Drivers include resource depletion and conflict, and social responses comprise self-organization, consensus building, and collective action. We share insights on key factors that affect these phases of emergence, drawing on empirical findings from our policy review and key respondent interviews. We conclude by describing ways that our findings can directly inform policy and planning in practice, including the importance of documenting the ‘creation story’ that spawned the new institutional arrangement, ensuring that enabling conditions are present, the complexity of defining community, the connection between process legitimacy and outcomes, and understanding the costs and timelines associated with co-management governance transitions.     

北京市1996-2007年住宅空调致冷耗能影响因素分析

 采用气象资料和经济统计资料,以北京市为例,分析了城镇住宅空调致冷耗能的影响因素。结果显示：在一定建筑设计标准下,直接影响城镇住宅空调致冷耗能的因子主要有降温强度、城镇人口数、人均住宅建筑面积和城镇家庭空调器拥有比例。总的来说,由于目前中国城市化进程的加速,城镇人口、人均住宅建筑面积、城镇空调器拥有比例在不断增加,因此,无论气候变暖或变冷,各地空调致冷耗能不可避免地在增加。在上述因子中,气候是目前为止唯一可能起到降低能耗作用的因子。对于城市化较快的北京市,由于城镇家庭空调器拥有比例的快速增长,城镇家庭空调器拥有比例这一因子对空调致冷耗能增量的贡献率普遍最大。

Statistical analysis of the temporal and spatial controls on tidal signal preservation in late-Holocene tidal rhythmites, Romney Marsh, Southeast England

A hierarchical series of tidal periodicities are preserved within laminated tidal flat deposits at the barrier/back-barrier interface of Romney Marsh and the Dungeness Foreland in southeast England. The sedimentary record of the tidal signature, extracted from variations in sand layer thickness, was found to be severely truncated with neap-spring periods typically represented by five or less sand layers and possibly only alternate neap-spring periods present. Despite the low number of sand layers deposited in these higher frequency tidal cycles, semi-annual periods are clearly preserved but tend to contain less than the expected 6 months of sedimentation. Annual accumulation rates of around 0.2–0.3 m/year are indicated. Local emplacement of storm beaches is considered to have created the protected conditions suitable for tidal rhythmite preservation. Ongoing foreland progradation and infilling eventually restricted tidal inundation to the point where distinct sand laminae were no longer deposited. Here, in contrast with other systems, accommodation space was not limiting and tidal flat elevation is reflected as a more subtle control on spatial changes in the resolution of the tidal signal.     

Map-Based Web Tools Supporting Climate Change Adaptation

This article discusses the state of the art in geovisualization supporting climate change adaptation. We reviewed twenty selected map-based Web tools, classified by their content and functionality, and assessed them by visual representations, interactive functions, information type, target audience, and how vulnerability and adaptation to climate change are addressed. Our study concludes that the tools (1) can be classified as data viewers with basic functionality and data explorers offering more sophisticated interactive functions; (2) mostly feature moderate or high richness of data content; and (3) predominantly target expert users.
